Pretty durable, good range, programmable with the flipper zero.

zoomzoom870—June 28, 2025

Fits like it should, easily programmed with the flipper zero. Functions as a much more convenient replacement for my badge to access work. I actually bought this one to replace one I've had for about 2 years that finally broke. The white almost immediately got all kinds of cracks in it but was perfectly fine for all that time but the entire thing is ceramic apparently so one good bump against a diamond ring and it finally had enough. For my friends using the flipper zero you want the blank version. It's got a lot bigger range than the ID card I copied to it and even works well through gloves. If you ride a motorcycle and need to get through a gate at work being able to simply fist bump the card reader without having to stop and take your gloves off and get your wallet out is awesome.

Exactly what I needed

Jonathan Quesnell—October 9, 2023

Works perfectly for my work key fob. It has yellowed a little over several months of constant wear, but that was expected, and I'm not easy on jewelry anyway. (Please excuse my horrible nails 😅) Read more
